Scuderia Toro Rosso driver Sébastien Buemi drives the Red Bull Racing running showcar in an exclusive winter session on Circuit Gilles Villeneuve, and an incredible ice run on the frozen waters of northern Quebec. The car, a 10 cylinder, Cosworth-powered STR1, was fitted with a one-of-a-kind set of Bridgestone Potenza F1 snow tyres and featured 420 tungsten studs on each of the front and 588 studs on each of the rear tyres, each one embedded in an aluminium casing.
